In a method for downloading subscription information to an identification unit connected to a wireless communication device operating within a cellular network, which includes at least one packet gateway node and a remote provisioning server being connected to it, the wireless communication device operates in a mode with limited access to the remote provisioning server. The method includes submitting a request comprising an authentication identifier and access information relating to one remote provisioning server from the identification unit on an assigned communication channel to the cellular network, forwarding at the cellular network said request using a connection tunnel preconfigured according to said access information from the packet gateway node to the remote provisioning server addressed by said access information, and providing a response message comprising data relative to subscription information through said preconfigured connection tunnel to the identification unit, when subscription information is detected.
